I can t turn on the machine, what s going on, solve it

There is a boot hard drive reflashing on the line.

1. Check the cause of the failure.

If the Dell laptop can't be turned on, you must first analyze the cause of the failure according to the specific situation, and you need to know whether it is a poor power supply contact or a hardware problem. Power supply problems go to [Power Supply Troubleshooting] below; If you can't enter the system, it may be an operating system or software problem, go to [System Troubleshooting] below.

2. Power supply troubleshooting.

Check if there is a problem with the power supply and see if the power supply and plug are not plugged in properly. You can use the same model of power supply to try it, after replugging the power supply, see if it can be turned on, if you change someone else's power supply to turn on, that is a problem with the power supply. If it turns out that there is no problem with the power supply and the laptop still won't turn on, it may be due to the hardware, go to [Hardware Troubleshooting] below.

3. System troubleshooting.

For system troubleshooting, you need to adjust the correct configuration, press and hold F8 to enter the advanced options page when you boot up, and select [The Most Recent Correct Configuration]. If it can enter the system, it may be caused by viruses, hardware drivers that are incompatible with the system, operating systems, etc. After entering the system, run antivirus software to kill the virus.

After the virus detection is completed, it is not normal to restart the computer. It may be caused by the incompatibility of the device driver with the program, delete the graphics card, network card and other drivers, and restart again to continue the problem, then go to the next step [Reinstall the system].

Fourth, reinstall the system.

Repair the installation or reinstall the system, set it up in the BIOS"The optical drive is the first boot device", then insert the system disk and press the R key"Repair the installation"。If the fault persists, just at the beginning of the system, select"One-click GOST to restore the system"Alternatively, use the system disk to reinstall the system.

5. Hardware troubleshooting.

There is still a problem with the above operations, so you need to check whether there is a hardware problem, and disassemble the notebook to check the hardware. If the hardware is loose and not plugged in, there will be an alarm sound, a long sound that keeps ringing means that the memory module is not plugged in tightly, one long and one short means that there is a problem with the memory or motherboard, and one long and two short means that the graphics card is wrong. Pay attention to whether it is caused by hardware incompatibility, if it cannot be started at this time, then you need to send it to a professional for repair, and check whether there is a problem with your hardware one by one.

The boot of the DOS system is broken,If there is a system restoration, you can click continuously when you boot up, probably F8 can enter the interface。

You connect the charger and then press the power button to see if the phone shows the charging status, if it does not show, it is recommended to tear off the power and then press and hold the power button for about 10 seconds to reset the phone, this is to prevent the crash caused by the boot can not be afforded, and then connect the charger to try, if it still does not show charging, you replace the data cable and the charger to try, and then charge the machine for about half an hour, long press the power button for 10 seconds to see if the machine can be turned on, if the machine can not be turned on, it is recommended that you take the machine to the local customer service center for testing and processing.

If you have any other questions, you can enter the OPPO enterprise platform to ask customer service questions!

The BSOD issue can be solved in two of the most common scenarios:

1. Turn off the machine (if the short press of the power switch is invalid, press and hold the switch until the power indicator goes out or directly unplug the power cord), turn on the chassis after powering off, replug and unplug the memory stick, and wipe the gold finger with an eraser in one direction (the back of the thumb fingernail is also fine), and then turn on the machine after installation (before operation, you should also touch the wall with both hands to release your static electricity or wear anti-static gloves). If you don't know how to operate, then it's simple: a palm or kick on the chassis is fine (note the location:

The front of the shell on the left and right sides of the chassis without an interface in the back; Attention Tract: Don't push too hard). The above may need to be repeated, and if it doesn't work, you need to replace the memory module.

If you have more than two memory modules, you need to test them one by one.

2. Reinstall the system.

Press F8 to select the last correct launch of this option, if it doesn't work, you can only reinstall!

It seems that the blue screen caused by the system has just been installed, whether there is a hidden partition before the system, and whether the CPU is overclocked.

This is a disk problem, the system is checking, there is a number in the last row, that is the progress. Just wait.

Problem analysis: The computer automatically enters the CMOS interface of the motherboard when it is turned on, if you rule out human error to enter (you can press the ESC key to exit), it means that the computer fails to pass the self-test when it is powered on, which is generally a CMOS parameter error or hardware failure. Common phenomena include battery failure, misconfiguration, poor contact of local memory or hard disk, etc., which need to be investigated one by one.

Solution: 1. Battery failure: cause the computer to call the default parameters of CMOS, if it is inconsistent with the local hardware environment, the computer cannot be started normally.

You can purchase a motherboard battery to replace it, then turn on the computer and press the DEL button (F2 or other designated hotkeys for notebooks) to enter the CMOS interface, and reset the correct parameters, and finally press F10 to save and exit the reboot.

2. Configuration error: This situation will also occur due to the manual configuration of CMOS parameters that do not match the local hardware environment. In general, according to the prompt information on the black background and white text on the screen, press the F1 key to skip the non-fatal error and start the computer directly, or press the del key to enter the CMOS, and then press F9 to load the predefined parameters or select Load optimized defaults (load high-performance defaults) or Load Fail-safe defaults, and then press F10 to save and exit the restart.

3. Hardware failure: If the above operations are invalid, it means that there is a problem with the hardware, generally because the memory and the hard disk are in contact with Biliang or the hard disk master boot record is damaged, and the memory or hard disk needs to be reinserted and removed, or the hard disk master boot record is repaired or the system is reinstalled or the hard disk is replaced.
